HORATIO J. BREWER, OF NEWV YORK, N. Y.

ELECTRIC CONNECTION.

SPECIFICATION forming part of Letters Patent No. 451,364, dated April 28, 1891.

Application filed September 5, 1890- Serial No. 364,019. (No model.)

To all whom it may concern.-

Be it known that I, HORATIO J. BREWER,

of the city, county, and State of New York,

have invented anew and useful Improvement in Battery, Switch-Board, and other Electrical Connections, of which the following is a speci; fication.

In connecting electric conductors to batteries, switch-boards, and the like it often happens that through galvanic action, or owing to the moisture or other disturbing elements in the air, the parts become corroded from galvanic or chemical action, which interferes with the passage of the electric current and often practically destroys electrical connection. In order to overcome this objection it has heretofore been proposed to provide the terminals of the conductors with tips or connecting-picces, which are secured to the conductor by solder or other means and which form a convenient connection between the conductor and binding-screw ofthe battery or other appliance; but these tips are still subject to a greater or less extent to the same destructive action.

The object of my invention is to overcome these objections and to furnish a conductor terminal by which the connection between the conductor and other appliances can be made without danger of destruction from the causes set forth; and to these ends my invention consists in aconductor-terminal in which the wire is surrounded by a sheathing of practically non-corrosive metal, such as tin, applied directly to the end portion of the conductor.

In the accompanying drawings, Figure 1 is a side view of a wire having myimprovement applied to it. Fig. 2 is a side view of the same as seen in a different plane. Fig. 3 is a crosssection taken at the plane of the dotted line a: so, Fig. 1. Fig. 4 is a side view of a wire having my improvement applied to it in a slightly-different form. Fig. 5 is a side View of a wire having my improvement applied to it in still another form.

Similar letters of reference designate corresponding parts in all the figures.

A designates a wire such as is ordinarily used for an electric conductor. It will ordinarily be surrounded throughout its main portion by an insulating-cover A of any suitable character. The end portion which is to be connected with some other electric conductor is, however, bare.

B designates a sheathing applied to the end portion'and consisting of a film or sheet of tin. In Fig. 1 this film or sheet is bent longitudinally, or, in other words, in a line parallel with its side edges, and applied to the bare end portion of the wire. It is made more than wide enough to cover the bare portion of the wire, and its edges are pressed tightly together, as may be best understood by reference to Fig. 3. 1 have inFig.l shown part of this film or sheet bent outward or away from the opposite part to expose the bare end portion of the wire to view. Fig. a represent-s a similar film or sheet applied to a bare end portion of wire; but here the extremity-of the wire is twisted around the opposite portion, instead of simply being bent parallel with the main portion, as in Fig. 1.

In Fig. 5 the film or sheet of tin is simply wound spirally around a bare end portion of the wire.

The tin covering is very advantageous, as it will practically prevent galvanic action between the wire and some other conductor of electricity where otherwise galvanic action would be apt to occur if a damp atmosphere were present.

It will thus be seen that my improved tcrv minal practically consists of the conductor itself covered with a metallic sheathing applied directly thereto, and that the conductor and its sheathing can be bent or twisted to form a connector between the body of the conductor and the device to which it is attached.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A conductor-terminal consistingof a bare wire having a sheathing of practically noncorrosive metal applied to its end portion and made in the form of a thin film or sheet wrapped orfolded overthe bare portion of the wire and constituting a connector for the conductor, substantially as described.

2. A conductor-terminal consisting of metallic wire having a sheathing of tinwrapped or folded over the bare portion of the wire and constituting a connector for the conductor, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

' HORATIO J. BREWER.
